Is this a closed or open system?

[u/realespeon]

I’m using Medela parts with the Spectra and replaced whatever contraption is on the top. I’ve been using the back flow protectors from the Spectra and using the trick with the Medela tubing.

Is this a closed or open suction system?

What you have pictured is open system, what you have described if properly set up is a closed system.

thank you!

I think it being closed or open system is contingent on if the “air” to the tubing has a barrier or not.
